A shipping container will be used to transport several 100-kilogram crates across the country by rail. The greatest weight that
natulia [17]

Answer:

x ≤ 207 crates

Step-by-step explanation:

Greatest weight of the container = 27,500 kilograms

Weight of other shipment = 6,800 kilograms

Weight of a crate = 100 kilograms

Number of 100-kilogram crates that can be loaded into the shipping container = x

The inequality is

27,500 ≤ 6800 + 100x

27,500 - 6800 ≤ 100x

20,700 ≤ 100x

x ≤ 20,700 / 100

x ≤ 207 crates

Adding or subtracting fractions with different denominators
Bas_tet [7]

Step-by-step explanation: You can't continue on with the problem until the denominators are the same. So you need to find the LCD (Least Common Denominator). For example...

\frac{1}{2} +\frac{1}{3}  The LCD is six

\frac{1*3}{2*3}=\frac{3}{6} =\frac{1}{3}

\frac{1}{2}+ \frac{1}{3}= \frac{3}{6} +\frac{2}{6}

\frac{3+2}{6}= \frac{5}{6}

Hope this helps, have a BLESSED and wonderful day! :-)

What is a necessary step for constructing perpendicular lines through a point on a line?
maxonik [38]

Answer:

Edit: This is incorrect, it might actually be the 3rd answer, draw arcs on either side of a given point on the line?

Draw arcs on either side of a given point off of the line I believe.

Step-by-step explanation:

Bisect a Segment:

Step 1 - open up your compass so that it is slightly larger than the segment. Put the compass on point A on the given segment and swing an arc above and below the lines. Do the same on point B. Create the points where the circle intersects.

Step 2 - Draw a line going through the points. That’s the bisector.

Find an ordered pair (x, y) that is a solution to the equation 4x + y = 1
Mila [183]

Answer:

(0,1)

Step-by-step explanation:

There are infinite number of (x,y) pairs in a line, so it should be easy to use any value for one of the coordinates (x or y) and find what the other coordinate should be. We can use a simple value that would make our solving easy, for example x = 0. We use this value to replace x in the equation of the line, and solve for y:

4x+y=1\\4(0)+y=1\\0+y=1\\y=1

Therefore the pair (0,1) is a solution for the given equation.
